[PATCH 1/1] tracing: fix spelling mistakes

[Zhen Lei <thunder.leizhen@huawei.com>]

Fix some spelling mistakes in comments:
wont ==> won't
overwite ==> overwrite
outputing ==> outputting
overlayed ==> overlaid
singe ==> single

The name of an unused function parameter:
ingore ==> ignore

And the name of the cpuhp step:
preapre ==> prepare
